CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 239,018, dated March 22, 1881.

Application tiled July 26, 1880.

' lowing is a specification.

ygitudinal section at the axis of the axle.

The object of my invention is to provide a car-axle box which is convenient of access, uniform and even in the bearing and wear of its movable parts, strong and durab e, and which shall permit an easy motion of he car-body with which it is connected, and accomplish these objects by the mechanism hown in the accompanying drawings, which is an improvement upon the patent granted to Ine September 4, 1877, No. 194,801.

Figure I is a side view of a car-axle box having my invention applied. Fig. II is an end view of the same. Fig. III is a vertical lon- Fig. IV is a half plan view of the pedestal and box together, and a half plan view ofthe box alone, and Fig. V is a plan view of the brass which takes the bearin g of the axle.

In the drawings, B represents the box proper, or that portion which contains the oil, and in which are located the bearing pfrtions of the axle, and upon the lower side ,of the upper portion of which is cast a lug 3, (shown in Fig. III,) which lug projects down by the side of the stud 2 on the brass 16,/to stop the latter from moving inward outot place, the key 4 at the outer end ot' the axl preventing the brass from moving outward,l and this forked key 4, which is movable innlvertical grooves 17 in the sides of the box, also straddles the grooved outer end of the axle and keeps the latter in its proper relative position with and in the box.

The cap C is provided at its upper end with a projection, 8, on the inside, which is inserted into a recess, 10, in the upper side of the box, near its outer end, and the cap `is provided with a recess, a, with a hole in the bottom, to receive a bolt, 1, inserted downi through the (No model.)

outer end of the box, with a nut turned on the lower end, which secures the cap in place upon the box.

The pedestal D is secured to the sillE (shown indotted lines) of the car by bolts b, and is provided with jaws D whichextend down over` each side of the box B, and a spring, F, is secured to the inner end of each bolt b by check-nuts 1l, and extends down on each side the box, with its lower end arranged to bear against the housing A and its upper part to bear against a lug, 5, cast upon the inside ot the upper part of the pedestal, and the spring is prevented from vibrating in one directionthat is, in a direction lengthwise the car`by the lugs or projections (Lon the pedestal. This spring may befadjusted to bear more or less against the housing A by turning the nuts 11 more or less onto thel 'bolts b. The steps 7- one on each side the box to supportthe springare each secured by two braces-one, as at I, extending from the step to the box, and the other, as at I', extending from the step to' the housing A, which construction renders the whole much stronger and much more rigid.

The brass 16, which sustains@ the bearing of the axle H,"is made with both ends alike, so that the brass may be inserted ither end iirst, and its ends are elongated, wit a hole, 18, in each if desirable, by which to draw the brass out of the box conveniently with a hook when the cap C is removed for that purpose.

Having thus described my invention, what I claim as new is- 1. The combination of the axle, having no brass-retaining collar of greater diameter than its bearing-surface, with the box, adapted to contain the axle and its bearings, provided with a single lug, as 3, projecting down inside, and a movable brass provided with a single stud,

as 2, projecting upward to bear against saidl gle stud, as 2, to operate in connection with a single lug, as 3, projecting down from the axlebox above, and formed with elongated ends, each having a hole therein, substantially as Iand for the purposes set forth.
